    i have a 496 (or whatever) which is the aviation version of the 276. i think i can only update TOPOS through garmin so i am considering going to open street maps. currently street maps from garmin are old and it does not appear to be updateable.

    can you update maps on a 276?

    anyone converted to openstreet maps and only use these without the proprietary garmin maps on these devices?

    THANKS

    The answer to your first question is "yes, but..." the qualification being that Garmin stopped issuing City Nav in DVD format. If you can find a DVD with a keycode not already tied to a specific unit, then you can upgrade the maps on a 276/496. More info in this thread:

    I've used openstreet maps in the northeast US on my 376C. On the street, they're OK but I think not as good as Garmin City Nav. The openstreet maps TOPO maps, however, I really like and think they're better than the Garmin TOPO.

    hi drew. thanks a lot. also much appreciation for bringing the link to my attention. i’d seen it before but somehow my brain periodically gets vapor locked on this stuff despite having a healthy ability to work in/on the computer.

    so just quickly (i am going to print out the thread and read it cover to cover now that i am “all in”).

    i need “an ‘unregistered’ City Navigator (keycode not used)” which i can load into my PC and register to MY UNIT, will upload to my computer and that will the allow me to /download/ an update from Garmin to the hard drive and then to the unit?

    is it possible that i /already/ have a City Nav registered to the unit but that they don’t allow updates for the 496?? i mean i posted on this elsewhere but because it takes me awhile to figure out what is going on it is complicated for me. bit i thought the guy at garmin said i /can’t/ update the road map and can only buy topos for this unit.

    any help or corrections really appreciated...

    THANK YOU

    It's a confusing topic but here is how I understand it. For starters, yes, you do need an " ‘unregistered’ City Navigator (keycode not used)” which i can load into my PC and register to MY UNIT..." You will have to get it somewhere other than from Garmin. Since Garmin stopped issuing CNNA on DVD, you will not be able to get the most current version but depending on how old the version is on your unit, it may still be worth doing. That will be it for an update. You will not be able to get any further updates for CNNA for the unit from Garmin.

    It's beyond frustrating that Garmin no longer supports these great GPS's. Openstreetmaps might be your best option.

    thanks drew. i need the heads ups!

    so from the looks of the image i posted i have CNNA registered to this unit and garmin sees it. from talking to the agent there is no update to this map. of course until you explained it i didn’t really understand this was a lack of support issue so i found it super confusing. now i get it.

    i need to print out that thread (hopeless paper reader over here) but - is there a good tutorial for loading openstreetmap? it does not get loaded via the garmin software i assume?

    is there a manual deletion of the garmin map to get the OSM on there?

    is it possible an ancient CNNT is /better/ than the new OSM?

    maybe i should try riding with the ten year old CNNT for awhile and then make a call on moving to OSM as i research loading street maps and topos...?

    maybe i need to swing by some airplane place and noodle around to see if anyone works with these...

    Answers attempted in red.

    Must be online forums for the airplane guys as well.
